Total Knee Replacement Surgery in India
A total knee replacement replaces your diseased knee joint and eliminates the damaged bearing surfaces that are causing you pain. The design of the implant offers you renewed stability and minimizes the wear process. Overall there are three benefits from your knee replacement: Elimination of pain Improved motion Minimum wear and tear Total knee replacement offers the greatest quality of life improvement of all operations. It has one of the highest success rates and one of the best outcomes. KNEE REPLACEMENT COMPONENTS The lower part of the replacement knee joint is comprised of a flat metal plate and stem that your surgeon will implant in the tibial bone, as shown in the movie above. This tibial tray can be either cobalt chrome alloy or titanium alloy. It can be fixed by either cement or bone “ingrowth”. Next, a polyethylene insert is clipped into the tibial tray to serve as the new knee bearing surface. The upper part of the replacement knee joint consists of a contoured metal shield that fits around the lower end of the thigh bone (femur). The inner surface can be fixed to the cut bone surfaces by the surgeon’s choice of bone ingrowth or bone cement. The outer surface of the contoured metal shield is shaped to allow the knee cap (patella) to slide up and down in its groove. The surgeon may choose to retain the natural knee cap or re-surface it. In this case a polyethylene button will be cemented in place. TOTAL KNEE REPLACEMENT IMPLANTS A diagnosis of advanced osteoarthritis of the knee will indicate the need for total replacement of the knee joint. Based upon your age and lifestyle, there are several design options to choose from that will help you return to an active enjoyable life. FIXED BEARING The polyethylene cushion may be part of the platform (fixed) or free to move on a metal base (mobile). Most people get a fixed-bearing prosthesis that reduces knee pain dramatically and may last for many years. If you are younger, more active and/or overweight, sometimes a doctor may recommend a mobile-bearing or a rotating platform knee replacement designed for potentially longer performance with less wear. Doctors also consider gender, occupation, disability level, pain intensity, interference with lifestyle and other medical conditions in selecting the appropriate prosthesis. MEDIAL PIVOT The Medial-Pivot knee replicates the rotating, twisting, bending, flexion, and stability of your natural knee, so it feels more like your natural knee. A normal knee actually pivots on its medial (inner side) condyle. When the knee flexes, the lateral (outer side) side rolls back while the medial side rotates in one place. This design "stays put" or is more stabile during normal knee motion as opposed to sliding forward slightly. ROTATING PLATFORM AND MOBILE-BEARING Knee implants imitate the motion of your natural knee. In the Rotating Mobile Knee prosthesis, the polyethylene insert can rotate slightly around a conical post. It also slides back and forth on the tibial tray. This allows the knee to twist and turn (called rotation), as well as move back and forth, flexing and extending (called articulation). The insert absorbs forces across a larger contact surface, helping reduce the amount of wear to the bearing and loosening in places where the implant attaches to bone. However, compared with Fixed-Bearing designs, Mobile-Bearing knee implants are less forgiving of imbalance in soft tissues. They may increase the chance of dislocation and may cost more than Fixed-Bearing implants. POSTERIOR CRUCIATE LIGAMENT (PCL) - RETAINING OR SUBSTITUTING The Posterior Cruciate Ligament is one of the major ligaments in the knee. It provides support and stable movement of the knee. In total knee replacement surgery, the PCL can be kept or removed and this choice depends on the condition of the PCL, the type of knee implant or the type of surgery the surgeon likes to do. Each of these designs has advantages and disadvantages. Surgeon preference depends on his or her training and the clinical situation. PCL-RETAINING In PCL-Retaining designs, rearward movement of the tibia is resisted by an intact PCL, which creates stability. PCL-SUBSTITUTING PCL-Substituting knees (also called posterior stabilized knees) have a raised sloping surface or a polyethylene post that compensates for the missing PCL to give your knee more stability. SPECIAL NEED KNEE IMPLANTS NARROW FEMUR VS. NORMAL FEMUR People with smaller skeletons present challenges that require the adoption of implants constructed for their special needs. Research shows that regular-sized implants may overhang on the bone and lead to soft tissue interference or mid-flexion instability in those people with narrow femurs. Implant manufacturers are now introducing special need implants for smaller than average patients. These new implants (represented in teal in the image to the right) are designed to accommodate those male or female femora with smaller than average dimensions. This helps ensure the special need patient will receive the best implant fit possible. CUSTOM FIT THROUGH GRADUATED SIZING An important issue for knee implant design is how the kneecap moves against the new femoral component. Knee implants are designed with a groove, or track, that the kneecap rides in as the leg straightens and bends. How this track is designed is important because it partially determines how mobile the knee is and, to a certain extent, the level of comfort the implant provides. Implant manufacturers who offer a broad range of implant sizes will best be able to fit special need patients. This is important because implants that are too wide can hang over the bone and irritate the soft tissues in the knee. RESURFACING AND PARTIAL KNEE REPLACEMENT IMPLANTS Sometimes the deterioration of the knee joint is such that total knee replacement can be avoided and your surgeon may suggest resurfacing or partially replacing components of your arthritic knee. Preserving healthy bone stock is especially important to younger and more active individuals. PARTIAL KNEE RESURFACING Partial Knee Resurfacing is an innovative procedure designed to provide quicker recovery and improved surgical outcome for patients with osteoarthritis in only one part of the knee. By selectively targeting the portion of the knee that has become damaged by osteoarthritis, surgeons can isolate and resurface only the arthritic portion of the knee without compromising the healthy bone and tissue surrounding it. This procedure is made possible through a surgeon-interactive robotic arm system. This system allows the surgeon to pre-operatively determine the damaged area of the bone to be removed and to plan the precise alignment and placement of the resurfacing implant specific to the patient’s anatomy. This level of consistently reproducible precision enables surgeons to restore knee function by resurfacing the arthritic defects rather than replacing the entire knee. UNI-COMPARTMENTAL PARTIAL KNEE REPLACEMENT A partial knee replacement -- also called a uni-compartmental knee replacement -- involves putting an implant on just one side of the knee, rather than over the entire surface of the knee joint. Think of the knee as having three compartments: an inside, outside, and a front compartment for the kneecap. Most frequently, it is the inside compartment that becomes arthritic. A uni-compartmental knee replacement is done if part of the knee joint is damaged by arthritis and the other compartments have healthy, normal cartilage. By retaining undamaged parts of the knee, the joint may bend better and function more naturally. This Uni-compartmental Knee System is offered in two designs, inlay and onlay. Your surgeon will determine which implant design would be best suited for your knee. The inlay implant is designed to restore the natural function of the knee by playing the role of the cartilage lost to osteoarthritis. It is comprised of two components: the femoral component (affixed to the femur bone) and the tibial component (affixed to the tibia bone). These components are implanted using a surgeon-interactive robotic arm system to ensure precise alignment and accurate placement. When the procedure is complete the components work together to provide a smooth surface for your knee joint to operate more naturally, like it did before osteoarthritis took its toll. The onlay implant is also designed to restore the natural function of the knee by playing the role of the cartilage lost to osteoarthritis. It is comprised of three components: The femoral component (affixed to the femur bone), the tibial base plate (affixed to the tibia bone) and the base plate insert (affixed to the tibial base plate). These components are also implanted using a surgeon-interactive robotic arm system. KNEE INTERPOSITIONAL DEVICE This device, which is modified for each individual, allows patients to return to light to moderate physical activities in short time. It can delay the need for further surgery by redistributing joint stresses and preserving the bone structure in the joint. The device closely matches the normal joint geometry, permitting the femur (thigh bone) to articulate against a smooth implant surface. Because the implant conforms to the bony structure of the tibia, it stays in place without the need for cement or screws. In a healthy knee, the meniscus serves as a shock absorber between the ends of the bones. The implant to the right features an artificial meniscal bearing designed to glide freely throughout the knee's range of motion, more closely replicating normal movement. The free floating nature of the device also improves durability of the implant. The implant to the right is designed using Computed Tomography (CT) images of the patient's knee. The implant is manufactured using anatomical information derived from these images, thereby achieving a custom fit for each patient. The advantage of this type of implant is that only the damaged cartilage from the weight bearing portion of the femur is removed. It is resurfaced with a cobalt chrome implant that conforms precisely to the anatomy of the knee. The tibial component is made of polyethylene and only requires minimal bone removal to secure the implant. BI-COMPARTMENTAL PARTIAL KNEE REPLACEMENT As osteoarthritis progresses, and the patient is no longer a candidate for a uni-compartmental implant, a total knee replacement has been the only treatment option available. The bi-compartmental implant was developed to address this particular need, that is, when a standard uni-compartmental procedure is not indicated and a total joint replacement is not required or desired, for example due to disease in only two compartments or younger age. The implant shown here is made specifically for an individual patient from their CT scan. Its unique design preserves the unaffected portions of the knee, maintaining the stability and natural properties of the joint. CEMENTED OR CEMENTLESS FIXATION Knee replacements may be “cemented” or “cementless” depending on the type of fixation used to hold the implant in place. The majority of knee replacements are generally cemented into place. Cemented knee replacements have been used successfully in all patient groups for whom total knee replacement is appropriate, including young and active patients with advanced degenerative joint disease. 15 years of clinical reports support this conclusion. Implant designs were introduced in the 1980's that were intended to attach directly to the bone without the use of cement. Cementless designs rely on bone growth into the surface of the implant for fixation. Most implant surfaces are textured or coated so that the new bone actually grows into the surface of the implant. Screws or pegs may also be used to stabilize the implant until bone ingrowth occurs. Because they depend on new bone growth for stability, cementless implants may require a longer healing time than cemented replacements. Each case is individual and your surgeon will evaluate your situation carefully before making any decisions. Do not hesitate to ask what type of fixation will be used in your situation, and why that choice is appropriate for you. TYPES OF POLYETHYLENE Polyethylene used in knee joints runs the gamut from non-cross linked (sterilized by ethylene oxide gas or gas plasma methods) to moderately-cross linked (gamma radiation sterilization). Generally speaking, increased cross linking results in wear reduction, but there are design variables of the implant to consider. Source: http://kneeortho.org/KneeReplacement.html
